Detailed Description

appends one or more composite datasets with the same structure together into a single output composite dataset

vtkAppendCompositeDataLeaves is a filter that takes input composite datasets with the same structure: (1) the same number of entries and -- if any children are composites -- the same constraint holds from them; and (2) the same type of dataset at each position. It then creates an output dataset with the same structure whose leaves contain all the cells from the datasets at the corresponding leaves of the input datasets.

Currently, only input polydata and unstructured grids are handled; other types of leaf datasets will be ignored and their positions in the output dataset will be NULL pointers. Point attributes (i.e., scalars, vectors, normals, field data, etc.) are extracted and appended only if all datasets have the point attributes available. (For example, if one dataset has scalars but another does not, scalars will not be appended.)

Member Function Documentation

static vtkAppendCompositeDataLeaves* vtkAppendCompositeDataLeaves::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkCompositeDataSetAlgorithm.

virtual const char* vtkAppendCompositeDataLeaves::GetClassName (  )  [virtual]

Reimplemented from vtkCompositeDataSetAlgorithm.

static int vtkAppendCompositeDataLeaves::IsTypeOf ( const char *  name  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCompositeDataSetAlgorithm.

virtual int vtkAppendCompositeDataLeaves::IsA ( const char *  name  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCompositeDataSetAlgorithm.

static vtkAppendCompositeDataLeaves* vtkAppendCompositeDataLeaves::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkCompositeDataSetAlgorithm.

void vtkAppendCompositeDataLeaves::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCompositeDataSetAlgorithm.

vtkCompositeDataSet* vtkAppendCompositeDataLeaves::GetInput ( int  idx  ) 

Get any input of this filter.

Reimplemented from vtkCompositeDataSetAlgorithm.

vtkCompositeDataSet* vtkAppendCompositeDataLeaves::GetInput (  )  [inline]

Get any input of this filter.

Definition at line 59 of file vtkAppendCompositeDataLeaves.h.

void vtkAppendCompositeDataLeaves::RemoveInput ( vtkDataSet in  ) 

Remove a dataset from the list of data to append.

virtual void vtkAppendCompositeDataLeaves::SetAppendFieldData ( int   )  [virtual]

Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.

virtual int vtkAppendCompositeDataLeaves::GetAppendFieldData (  )  [virtual]

Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.

virtual void vtkAppendCompositeDataLeaves::AppendFieldDataOn (  )  [virtual]

Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.

virtual void vtkAppendCompositeDataLeaves::AppendFieldDataOff (  )  [virtual]

Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.

virtual int vtkAppendCompositeDataLeaves::RequestDataObject ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
) [protected, virtual]

Since vtkCompositeDataSet is an abstract class and we output the same types as the input, we must override the default implementation.

Reimplemented from vtkCompositeDataSetAlgorithm.

virtual int vtkAppendCompositeDataLeaves::RequestData ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
) [protected, virtual]

Iterates over the datasets and appends corresponding notes.

Reimplemented from vtkCompositeDataSetAlgorithm.

virtual int vtkAppendCompositeDataLeaves::FillInputPortInformation ( int  port,
vtkInformation info 
) [protected, virtual]

The input is repeatable, so we override the default implementation.

Reimplemented from vtkCompositeDataSetAlgorithm.

virtual void vtkAppendCompositeDataLeaves::AppendUnstructuredGrids ( int  i,
int  numInputs,
vtkCompositeDataIterator iter,
vtkCompositeDataSet output 
) [protected, virtual]

When leaf nodes are unstructured grids, this uses a vtkAppendFilter to merge them.

virtual void vtkAppendCompositeDataLeaves::AppendPolyData ( int  i,
int  numInputs,
vtkCompositeDataIterator iter,
vtkCompositeDataSet output 
) [protected, virtual]

When leaf nodes are polydata, this uses a vtkAppendPolyData to merge them.

virtual void vtkAppendCompositeDataLeaves::AppendFieldDataArrays ( int  i,
int  numInputs,
vtkCompositeDataIterator iter,
vtkDataSet dset 
) [protected, virtual]

Both AppendUnstructuredGrids and AppendPolyData call AppendFieldDataArrays. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
